I would like to make a comment on that paper you cited as it relates to the test results. I am impressed by the authors' technology. I believe they are helping to advance the state of the art in IDS/IPS testing. However, ISS has been unable to reproduce the results that the authors describe with recent products. I believe that the authors were using older versions of ISS products during testing. So far, they have not provided product version information when asked. So, I strongly believe that the published results are not a reflection of the quality of recent ISS product protection. Even so, I still believe that the results demonstrate the strengths of the authors' technology to expose limitations in an IDS/IPS product whether or not the product is still relevant.

The tricks vary from protcol to protocol. The difference in the decoding mechanism of security appliance and the application server can lead to many evasion techniques. I have created and tested many mutant exploits and they worked beautifully. The idea is to strike and exploit some fundamental concepts of logic and protocols which IDS/IPS makers tend to ignore or is simply beyond their device capability Apparently, I haven't documented and organized the work I did. But here is an introductory paper you should definitely read: http://www.cs.ucsb.edu/~rsg/Hidra/Papers/2004_vigna_robertson_balzarotti _CCS04.pdf --Pukhraj Singh On 10/27/05, tcp fin <inet_inaddr () yahoo com> wrote:
Hi Guys , Any tips and tricks or good article on IDS/IPS evasion ? I have beautiful paper "Insertion, Evasion and Denial of Service: Eluding Network Intrusion detection". I need some pointers on RPC based evasion techniques. Regards, TCP FIN . __________________________________ Yahoo!
